Problem- A 6.72 g sample of a salt is dissolved in 100.0 g water, in a constant pressure calorimeter. The initial temperature of the water is 21.50 oC, and the final temperature was 18.63 oC. Calculate the heat of solvation for the salt, as J/g. Is the process endo- or exothermic?
I want you to explain the chemistry in this problem
